Sugar Motta started in Blaine's class in 4th grade and he thought she was wonderful. She had skin the colour of caramel with super pretty hair like the doll on his grandma's dresser and she seemed super confident. Once she even called him cute and asked him to be her partner in maths, he really liked that.
When he told Santana this she laughed in his face and said he had a crush on sugar .when he insisted he didn't she told him it's nothing to be embarrassed about because a load of guys had crushes on her.
The next week Blaine tried to see if Sugar liked him back, Brian said she did .He ran to Santana's after school and got there a whole 2 minutes before her , they walked up to the tree house when Blaine said he had an important question. "What do you do when you have a crush? Do you just tell them and then hold hands?" He asked looking down at his feet. "No silly , you do this!" Before Blaine got a chance to ask what, she grabbed his face and placed her lips on his and started moving them.
Blaine had no idea what to do he was only 8 and 3 quarters ,so he did what they do in that show Cooper watches and stuck his tongue in her mouth.
She squealed "ewwww!" pulled back and Blaine went pillar box red then she slapped him and he ran home ignoring her calls of 'sorry and 'come back!'. As soon as he got home he went to Coopers room and knocked the door angrily. "Come in!" Cooper called back and so Blaine trudged in and crossed his arms before he even got to say anything his brother asked about his cut knee but he said he'd tell him later. "Is that show you like , the one where they're all friends and the Italy guy kisses loads of girl's , just pretend!?" He shouted at Cooper .When he said yes and asked him why he wanted to know Blaine blushed a stared at his hands before mumbling "San kissed me and-" he was cut off by a "no way! You're like 6!" But he just said 'yes-way and I'm nearly 9!' and continued "so I did what Joey does and she slapped me in the face!". Copper paled and prayed to god his brother didn't do anything that would cause him to get into trouble for letting him watch that. "we were kissing so I stuck my tongue into her mouth-" Copper started laughing really loud.

He later discovered nearly 9 year olds don't 'make out' , they kiss just use lips.

That was the first time Blaine kissed Santana it was also his first kiss , not hers though, just her first 'tongue kiss'. It was also the first time he got a crush on 'Tana'.
